本文主要介绍在OpenHarmony上，基于RK3568移植开源GPU Mesa3D图形驱动，使用的基线版本是openharmony 的RK分支+kernel4.19+Weston。

注意：weston是老版本中使用的，新版中已使用renderservice替换。

1、获取openharmony rk分支版本代码

该基线版本是RK分支的OpenHarmony版本，选用此版本的原因是，该版本使能了闭源的GPU。

  1. 从官网上拉取代码

创建编译openharmony的docker，安装依赖，下载源码，以及编译

  1. 创建docker：
  2. podman run --name hm-rk -it -v /home/test/22-01-30_rk /:/home/openharmony swr.cn-south-1.myhuaweicloud.com/openharmony-docker/openharmony-docker-standard:0.0.7 /bin/bash  
  3. git config --global user.name "test"  
  4. git config --global user.email "test@com.cn"  
  5. git config --global credential.helper store  
  6. 安装依赖：
  7. curl -s https://gitee.com/oschina/repo/raw/fork_flow/repo-py3 > /usr/local/bin/repo  
  8. chmod a+x /usr/local/bin/repo  
  9. apt-get update && apt-get install -y binutils git git-lfs gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z1-dev ccache libgl1-mesa-dev libxml2-utils xsltproc unzip m4 bc gnutls-bin python3.8 python3-pip ruby libssl-dev  
  10.  pip3 install -i https://repo.huaweicloud.com/repository/pypi/simple requests        
  11. 下载源码：  
  12. repo init -u https://gitee.com/openharmonyrk/manifest -b master -m rk.xml --no-repo-verify    
  13. repo sync -c    
  14. repo forall -c 'git lfs pull'   
  15. 编译：
  16. bash build/prebuilts_download.sh  
  17. ./build.sh --product-name rk3568 --ccache  

编译成功，刷机后，能进入系统，但是没有图形，注意RK版本的代码本省不能进图形是正常的。

2、编译5.10内核

Mesa3D需要高版本内核支持，而RK分支使用的是4.19的内核，所以需要升级内核，当前开源鸿蒙中2022.1.10后主干代码支持kernel5.10，因此编译kernel5.10需要使用Master 1.10以后的代码版本，具体如下：

  1. mkdir hm-master && cd hm-master  
  2. podman run --name hm-master -it -v /home/test/hm-master/:/home/openharmony swr.cn-south-1.myhuaweicloud.com/openharmony-docker/openharmony-docker-standard:0.0.7 /bin/bash  
  3. git config --global user.name "test"  
  4. git config --global user.email "test@.com.cn"  
  5. git config --global credential.helper store  
  6. curl -s https://gitee.com/oschina/repo/raw/fork_flow/repo-py3 > /usr/local/bin/repo  
  7. chmod a+x /usr/local/bin/repo  
  8. repo init -u https://gitee.com/openharmony/manifest.git -b master --no-repo-verify  
  9. repo sync -c  
  10. repo forall -c 'git lfs pull'  
  11. bash build/prebuilts_download.sh  
  12. ./build.sh --product-name rk3568 --ccache --build-target kernel  

注意：文档中只有本小节，即编译510内核才需要使用主干1.10以后的代码版本，其它小节均使用的是RK分支版本代码。

1）修改DTS

修改out/kernel/src_tmp/linux-5.10/arch/arm64/boot/dts/rockchip/rk3568.dtsi适配开源panfrost，如下：

--- arch/arm64/boot/dts/rockchip/rk3568.dtsi-bak        2022-02-15 01:39:52.169152789 +0000                                                                                         +++ arch/arm64/boot/dts/rockchip/rk3568.dtsi    2022-02-15 02:02:42.096047298 +0000  @@ -1169,36 +1169,23 @@                                        };                              gpu: gpu@fde60000 {  -               compatible = "arm,mali-bifrost";  -               reg = ;  +               compatible = "rockchip, rk3568-mali", "arm,mali-bifrost";  +               reg = ;      -               interrupts = ,  +               interrupts = ,                               ,  -                            ;  -               interrupt-names = "GPU", "MMU", "JOB";  -  -               upthreshold = ;  -               downdifferential = ;  -  +                            ;  +               interrupt-names = "job", "mmu", "gpu";                  clocks = , ;  -               clock-names = "clk_mali", "clk_gpu";  -               power-domains = ;  -               #cooling-cells = ;  +               clock-names = "core", "bus";                  operating-points-v2 = ;      +               #cooling-cells = ;  +               power-domains = ;                  status = "disabled";  -               gpu_power_model: power-model {  -                       compatible = "simple-power-model";  -                       leakage-range= ;  -                       ls = ;  -                       static-coefficient = ;  -                       dynamic-coefficient = ;  -                       ts = ;  -                       thermal-zone = "gpu-thermal";  -               };          };      -       gpu_opp_table: opp-table2 {  +       gpu_opp_table: gpu-opp-table {                  compatible = "operating-points-v2";                      mbist-vmin = ;  @@ -1227,7 +1214,7 @@                  };                  opp-800000000 {                          opp-hz = /bits/ 64 ;  -                       opp-microvolt = ;  +                       opp-microvolt = ;                  };          };  

2）修改config配置

  1. cd out/kernel/src_tmp/linux-5.10  
  2. make menuconfig ARCH=arm64 

在graphic support中启用panfrost，

然后在Direct Rendering Manager取消选择Ignore drm ioctl permission，然后保存退出配置。

  保存配置，并退出。

使用新的.config配置覆盖rockchip_linux_defconfig配置，使用make-ohos.sh脚本编译时config才能生效，如下：

cp .config arch/arm64/configs/rockchip_linux_defconfig  

3）修改drivers/gpu/drm/drm_ioctl.c

修改out/kernel/src_tmp/linux-5.10/drivers/gpu/drm/drm_ioctl.c搜索关键字DUMB，将0修改为DRM_RENDER_ALLOW, 如下：

--- drivers/gpu/drm/drm_ioctl.c-bak     2022-02-16 02:16:18.211452279 +0000  +++ drivers/gpu/drm/drm_ioctl.c 2022-02-16 02:17:01.138864226 +0000  @@ -680,9 +680,9 @@          DRM_IOCTL_DEF(DRM_IOCTL_MODE_RMFB, drm_mode_rmfb_ioctl, 0),          DRM_IOCTL_DEF(DRM_IOCTL_MODE_PAGE_FLIP, drm_mode_page_flip_ioctl, DRM_MASTER),          DRM_IOCTL_DEF(DRM_IOCTL_MODE_DIRTYFB, drm_mode_dirtyfb_ioctl, DRM_MASTER),  -       DRM_IOCTL_DEF(DRM_IOCTL_MODE_CREATE_DUMB, drm_mode_create_dumb_ioctl, 0),  -       DRM_IOCTL_DEF(DRM_IOCTL_MODE_MAP_DUMB, drm_mode_mmap_dumb_ioctl, 0),  -       DRM_IOCTL_DEF(DRM_IOCTL_MODE_DESTROY_DUMB, drm_mode_destroy_dumb_ioctl, 0),  +       DRM_IOCTL_DEF(DRM_IOCTL_MODE_CREATE_DUMB, drm_mode_create_dumb_ioctl, DRM_RENDER_ALLOW),                                                                                    +       DRM_IOCTL_DEF(DRM_IOCTL_MODE_MAP_DUMB, drm_mode_mmap_dumb_ioctl, DRM_RENDER_ALLOW),                                                                                         +       DRM_IOCTL_DEF(DRM_IOCTL_MODE_DESTROY_DUMB, drm_mode_destroy_dumb_ioctl, DRM_RENDER_ALLOW),                                                                                          DRM_IOCTL_DEF(DRM_IOCTL_MODE_OBJ_GETPROPERTIES, drm_mode_obj_get_properties_ioctl, 0),                                                                                              DRM_IOCTL_DEF(DRM_IOCTL_MODE_OBJ_SETPROPERTY, drm_mode_obj_set_property_ioctl, DRM_MASTER),                                                                                         DRM_IOCTL_DEF(DRM_IOCTL_MODE_CURSOR2, drm_mode_cursor2_ioctl, DRM_MASTER), 

4）编译

PRODUCT_PATH="vendor/hihope/rk3568" ./make-ohos.sh TB-RK3568X0  

5）刷机

图中所示img全部使用新版内核中编译出来的img刷机，即master部分都需要刷入编译5.10内核出来的img，

3、编译Buildroot

编译环境：ubuntu20.04

1）下载代码

  1. git clone https://gitee.com/xfan1024/oh-buildroot-mesa3d -b rpi3b  
  2. cd oh-buildroot-mesa3d  
  3. apt-get install cpio ruby -y  

2）修改配置

  1. make mesa3d_rpi3b_defconfig  
  2. make menuconfig ARCH=arm64  

修改如下：

如果需要测试glmark2，还应该选中glmaster2

选中glmark2，然后保存退出，重新编译

3）编译

make -j8  

4）刷机测试

在system分区刷入buildroot编译出来rootfs.ext2镜像，刷机成功后，在终端运行glmark2-es2-wayland，验证内核panfrost驱动和用户态panfrost驱动是否可以正常工作，具体如下：

  1. mkdir /tmp/xdg  
  2. export XDG_RUNTIME_DIR=/tmp/xdg  
  3. weston --tty 1 &  
  4. glmark2-es2-wayland  

 

4、重新编译rk分支

1）找到编译好的二进制文件

将通过buildroot编译出来的二进制文件拷贝到rk分支的device/rockchip/hardware/gpu/中，

output/target/usr/lib/libEGL.so.1  output/target/usr/lib/libGLESv1_CM.so.1  output/target/usr/lib/libGLESv2.so.2  output/target/usr/lib/libgbm.so.1  output/target/usr/lib/libglapi.so.0  output/build/mesa3d-21.3.3/build/src/gallium/targets/dri/libgallium_dri.so  

2）修改rk分支代码对应的编译配置项

修改device/rockchip/rk3568/BUILD.gn

import("//build/ohos.gni")    print("rk3568_group in")  group("rk3568_group") {    deps = [    "//device/rockchip/hardware/gpu:libgallium_dri"    ]  }

修改device\rockchip\hardware\gpu\BUILD.gn为：

import("//build/ohos.gni")  import("//build/ohos/ndk/ndk.gni")    mesa3d_common_prebuilts = [    "libgbm.so.1",    "libEGL.so.1",    "libglapi.so.0",    "libGLESv1_CM.so.1",    "libGLESv2.so.2",  ]    mesa3d_common_deps = []  foreach(file, mesa3d_common_prebuilts) {    target = "mesa3d-common-$file"    ohos_prebuilt_shared_library(target) {      source = file      subsystem_name = "hdf"      part_name = "hdf"      install_enable = true    }    mesa3d_common_deps += [ ":$target" ]  }    group("mali-bifrost-g52-g2p0-wayland") {    deps = mesa3d_common_deps  }    ohos_prebuilt_shared_library("libgallium_dri") {    source = "libgallium_dri.so"    part_name = "rockchip_products"    install_enable = true    symlink_target_name = [      "panfrost_dri.so",      "rockchip_dri.so",    ]  }

3）重新编译

./build.sh --product-name rk3568 –ccache  

4）刷机

System、vendor、userdata 3个分区刷入rk分支新编译出来的img，

 刷机成功后，能正常进入系统，图形也正常启动，使用中速度明显感觉快了很多，即使输入wifi密码也能成功。

5、问题

1）内核编译报错：

 解决办法：

使用命令，  

PRODUCT_PATH="vendor/hihope/rk3568" ./make-ohos.sh TB-RK3568X0

2）内核刷机后进不了系统

把rk编译出来的img刷机后能进入系统，但是没有图形，把之前编译出来的rootfs.ext2和新编译出来的510内核boot_linux.img刷机后，串口显示如下：

解决办法：

有两种办法，一是把新老boot_linux.img 解压开对比

新老版中extlinux.conf对比发现都是类似的内容，唯一的区别就是有如TC031C的标识，串口输出中有找不到extlinux.conf.TC031C的打印

把old中extlinux.conf.TC031C拷贝到新版中，并复制toybrick.dtb为toybrick.dtb.TC031C

  1. cd new  
  2. cp toybrick.dtb toybrick.dtb.TC031C  
  3. cp ../old/extlinux.conf.TC031C ./  

重新刷入新的boot_linux.img，正常进入系统。

二是图中所示img全部使用新版内核中编译出来的img刷机（推荐该办法）。

3）编译buildroot报错

编译报如下：

  解决办法：

删除output目录，修改编译参数重新编译

  1. rm -rf output/  
  2. make -j8  

4）编译rk报错undefined symbol: wl_egl_window_create

错误提示如下：

ld.lld: error: undefined symbol: wl_egl_window_create  >>> referenced by simple-egl-hos.c:371 (../../third_party/weston/clients/simple-egl-hos.c:371)  >>>               obj/third_party/weston/clients/simple-egl-hos/simple-egl-hos.o:(main)    ld.lld: error: undefined symbol: wl_egl_window_destroy  >>> referenced by simple-egl-hos.c:418 (../../third_party/weston/clients/simple-egl-hos.c:418)  >>>               obj/third_party/weston/clients/simple-egl-hos/simple-egl-hos.o:(main)  clang-10: error: linker command failed with exit code 1 (use -v to see invocation) 

解决办法：

在third_party/wayland_standard/BUILD.gn中新增编译wayland-egl.c

5）编译rk报错undefined symbol: glEnable

错误提示如下：

使用nm -D 或者  objdump -tT 确定 glEnable 在哪个库文件中定义     

  1. nm -D libGLESv2.so.2  |grep  glEnable  
  2. 000068fc T glEnable  
  3. 00006918 T glEnableVertexAttribArray  
  4. 00006934 T glEnablei  

然后修改配置foundation/graphic/standard/frameworks/animation_server/BUILD.gn，增加对应的依赖，

--- a/frameworks/animation_server/BUILD.gn  +++ b/frameworks/animation_server/BUILD.gn  @@ -116,6 +116,7 @@ ohos_executable("animation_server") {       "//foundation/graphic/standard:libwmservice",       "//foundation/graphic/standard/utils:libgraphic_utils",       "//foundation/multimodalinput/input/frameworks/proxy:libmmi-client",  +    "//device/hihope/hardware/gpu:mali-bifrost-g52-g2p0-wayland",     ]       part_name = "graphic_standard"  

编译成功。

6）刷机进入系统后图形起不来

在终端执行ps -ef|grep weston，如果没有weston，即weston没有起来，如下：

原因则是weston.cfg配置中没有加入export LIBGL_DRIVERS_PATH /system/lib环境变量。

如果出现如下：

  1. # ps -ef |grep weston                                                            
  2. root           238     1 11 12:46:17 ?    00:00:22 weston -c /system/etc/weston.ini -B drm-backend.so --tty=1 --use-pixman  
  3. root           782   286 8 12:49:47 ttyFIQ0 00:00:00 grep weston  

最终定位到third_party/weston/weston.cfg 配置问题，weston服务启动时不能添加--use-pixman参数，如果有该参数，需要删除该参数，一下是基于RK分支代码weston的修改：

--- ../22-01-30_rk-bak/third_party/weston/weston.cfg    2022-01-30 15:37:09.000000000 +0800                                                                                         +++ third_party/weston/weston.cfg       2022-02-22 09:51:33.688896864 +0800  @@ -14,6 +14,8 @@                   "export XKB_CONFIG_EXTRA_PATH /etc/xkb",                   "mkdir /data/weston",                   "chmod 777 /data/weston",  +                "chmod 777 -R /dev/dri/*",+                "export LIBGL_DRIVERS_PATH /system/lib",                   "start weston",                   "trigger weston_start",                   "sleep 2"
